IMPROVEMENT IN STRAW-CUTTERS.

The Schedule referred to in these Letters Patent and making part of thename.

To all whom fit may concern.:

Beit known that I, HARRISON OGBORN, of Richmond, in the county of Wayne,and State otIndiana-,l

have invented a certain new and useful Fodder and Straw-Cutter andCorn-Sheller combined and I do hereby declare the following to be aclear description of' the construction and operation of the same,reference heilig had to the annexed drawings, making part of thisspecication, in which- Figure l is a perspective view of my improvedcombined straw-cutter and coru-sheller.

Figure 2 is a view of the left side of the same.

Figure 3 is a detached View of the spring for holding down the guide andpressure-board.

My improvement consists vin devices for adjusting the balance-wheel, forattaching the knives, and for holding down the pressure-board and upperroller of a straw-cutter.

A represents the feed-box. I5, the balance-wheel, carrying the `knives CC upon the radial arn'is D D, and furnished with Sheller-teeth, as shownat a c a a, upon the outside of the rim, which is made slightly concave.

The balance-wheel is attached to the end of the shaft E, which isscrew-tln'eaded, by I ueans of a'nnt or' hub, F. p

'Ihe hub is held in position by a pin, G, passing through holes c c inthe hub, and through the oblong or slotted hole X in `the shaft E.

11i this manner, the wheelmay he adjusted and slotted hole X, for thepurpose of retaining the balheld within a quarter of a revolution.

r lhc knives G C are attached directlyfto the arms D I), by means ofscrews s s s s, and are adjustable with the wheel by the devices justdescribed, so as to present a proper cutting-edge to the face-plate J.

Attached to the front right-l'laud post H is a toothed plate, I',supported vby a standard, K, the lower end of which is bevelled, so asto tit snugly to the t'ront of the post, and so-that it may be sprung inand adjusted by the holtv and screw L.

Ihis toothed plate is curved, so as, in combination with the concave rimof the balance-wheel, to form a space suitable for receiving and holdingan ear ot' corn, which, from the revolution of the balance-wheel, re-

- ceives a spiral motion as it passes down between the wheel and plateI.

'Ihe balance-wheel lshaft is operated by the bevellcdgear 'wheels M andN, the latter revolving upon the shaft O, which is the ci'ai1k-'sliait,and carries the lower roller. i

The upper roller V is geared, as shown-in ig.1, and held against thelower roller by ahook and rod, P, shown in dotted lines in lig. 2,attached to a springbar, Q, which is also bevelled at its upper end,where it is attached to the bottom of the feed-box, and v,ad-A justed byscrew WQ 'Ihe eogs upon' the rollers are made sufficiently long topermit them to be. separated sufficiently to allow lthe stra-w andihdder to passbetween them.

11n front ot' the feed roller is a pressure-board, VR, shown inred linesin ig.'1, and in dotted lines in fig. 2, which is held down upon thestraw or fodder by the bent spring Z, 'attached to the outside of thepost, as

post, and extending to thel board.

The spring may be adjusted by the screw T, so as to obtain'a greater orlessA pressure upon the board.

Vhat I claim as new and useful, and desire vto secure byALetters Patent,is-

1. The described mode of attaching two .knives to ter, in combinationwith the devices for adjusting the knives to the face-plate J, as hereinset forth.

2. Also, the combination of the pin G, holes c c, and

ance-wheel in any desired posit-ion upon the shaft, or of permitting oft-he adjustment of the knives, as described. v

3. Also, the adjustable spring Z, in combination wit-h thepressure-board It, when arranged as described, t'oxgthe purpose ofholding the straw and fodder compactly, as described.

4. Also, the combination of the spring-bar Q, when made adjustable, asdescribed, hooked rod P, and roller V, as and for the purposesdescribed.
